In today’s social media landscape, Instagram is hard to ignore. Founded on the basic concept of sharing images and getting people to like them, it has proven to be a powerful business tool (as well as a great place to showcase baby animals and young girls doing yoga). Even more than other channels, Instagram is driven by one fundamental metric – the size of your audience.

Facebook carousel ads show a sequence of up to five images, using headlines, text crawl, links and calls to action, all in a single ad unit. They have been a major product focus for Facebook over the past few years and can be used on all of Facebook’s channels, including Instagram.

Just a few short years ago, marketing funnels were relatively simple to track. But, with the explosion of channels, devices and platforms, marketing attribution has become increasingly hard to keep up with, even for smart CMO-types.
